Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique...

This document was developed in cooperation with the Minnesota Department of Health and staff at the Minnesota Pollution Control Agency (MPCA) Closed Landfill Programs to provide guidelines for the monitoring of methane associated with landfill gas (LFG) generated from abandoned unpermitted dumps that may pose risk to existing or proposed occupied structures. Non-methane organic compounds such a...

In January 1997, a pilot-scale project to assess the feasibility of in silu aerobic bioreduction of municipal solid waste was initiated at the Live Oak Landfill, located near Atlanta, Georgia The high costs (money, regulatory hurdles, societal objections) of developing new landfills are making fccovery and reuse of existing landfill space an increasingly attractive alternative. Onc bf the first...

Field investigations of lateral gas transport and subsequent emissions in soil adjacent to an old landfill in Denmark were conducted during a 1-year period. A significant seasonal variation in the emissions with high carbon dioxide and low methane fluxes in the summer (May to October) was observed. This was attributed to methane oxidation. Diurnal measurements during a drop in barometric pressu...

Methane gas is a by-product of landfilling municipal solid wastes (MSW). Most of the global MSW is dumped in non-regulated landfills and the generated methane is emitted to the atmosphere. Some of the modern regulated landfills attempt to capture and utilize landfill biogas, a renewable energy source, to generate electricity or heat. As of 2001, there were about one thousand landfills collectin...

In addition to leachate and gas emission analysis, temperature variations in municipal solid waste landfills are routinely monitored for safety and health reasons, such as the increased production of biogas or the danger of spontaneous combustion phenomena if the temperature exceeds 70– 75◦C. The increasing constraints on greenhouse gas emissions and the convenience of fuel and heat recovery ha...

The anaerobic decomposition of solid waste in a landfill produces methane, a potent greenhouse gas, and if recovered, a valuable energy commodity. Methane generation from U.S. landfills is usually estimated using the U.S. EPA's Landfill Gas Emissions Model (LandGEM). Default values for the two key parameters within LandGEM, the first-order decay rate (k) and the methane production potential (L0...
